Upper limb4

Axillary4

• These terminal branches are the musculocutaneous nerve, the axillary nerve, the radial nerve, the median nerve, and the ulnar nerve. (wikipedia.org)

• Diagram showing basic relationships of the brachial plexus to the pectoralis minor muscle and the axillary artery, which is a continuation of the subclavian artery. (medscape.com)
• [ 9 , 10 ] It enters the arm with the axillary artery and passes posterior and medial to the brachial artery, traveling between the brachial artery and the brachial vein. (medscape.com)

Nerves8

• Injuries associated with malpositioning commonly affect the brachial plexus nerves, rather than other peripheral nerve groups. (wikipedia.org)
• Due to the brachial plexus nerves being very sensitive to position, there are very limited ways of preventing such injuries. (wikipedia.org)
• The ventral rami of spinal nerves C5 to T1 are referred to as the "roots" of the plexus. (medscape.com)
• The spinal nerves that form the brachial plexus run in an inferior and anterior direction within the sulci formed by these structures. (medscape.com)
• The brachial plexus is formed by a union of anterior rami of the lower four cervical (C5 through C8) and the first thoracic (T1) spinal nerves between the anterior and middle scalene muscles. (brachialplexustreatment.com)
• Some nerve fibers to the plexus may originate from the fourth cervical (C4, prefixed) or from the second thoracic (T2, post fixed) nerves. (brachialplexustreatment.com)
• 1. Upper brachial plexus injury - It involves the C5, C6 spinal nerves and presents with a weak shoulder and elbow. (brachialplexustreatment.com)
• 2. Total brachial plexus lesion - It affects almost all the nerves of the plexus and presents with a flail limb without sensations. (brachialplexustreatment.com)

Spinal2

• This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand. (wikipedia.org)
• The brachial plexus provides nerve supply to the skin and muscles of the arms, with two exceptions: the trapezius muscle (supplied by the spinal accessory nerve) and an area of skin near the axilla (supplied by the intercostobrachial nerve). (wikipedia.org)

Nerve3

• The musculocutaneous nerve has even been shown to send a branch to the median nerve further connecting them. (wikipedia.org)
• The ligament of Struthers may occasionally cause neurovascular compression, usually involving the median nerve or the brachial artery but sometimes affecting the ulnar nerve. (medscape.com)
• Involvement of C7 nerve is termed as an extended upper plexus injury. (brachialplexustreatment.com)

Consist2

• The most common victims of brachial plexus injuries consist of victims of motor vehicle accidents and newborns. (wikipedia.org)
• This area mainly consist of the ossicles, eustachian tube and the tympanic plexus. (mskneurology.no)

Injuries1

• These injuries occur in approximately 4.2% of motor cycle accidents.1 Other less common modes of injury include automobile accidents, falls, sports injury, bicycle and pedestrian accidents, stab and gunshot wounds, inflammation ( Brachial neuritis or Parsonage Turner syndrome) and compression by tumors. (brachialplexustreatment.com)

Trunks2

• The brachial plexus is divided into five roots, three trunks, six divisions (three anterior and three posterior), three cords, and five branches. (wikipedia.org)
• The trunks of the brachial plexus pass between the anterior and middle scalene muscles. (medscape.com)

Cords2

• Most branches arise from the cords, but few branches arise (indicated in italics) directly from earlier structures. (wikipedia.org)
• The cords eventually divide into terminal branches. (brachialplexustreatment.com)

Sensation1

• Injury to the brachial plexus may affect sensation or movement of different parts of the arm. (wikipedia.org)

Tendon1

• The arcade of Struthers is formed by the attachments of the internal brachial ligament (a fascial extension of the coracobrachialis tendon), the fascia and superficial muscular fibers of the medial head of the triceps, and the medial intermuscular septum. (medscape.com)
